Humidity Measurement Explanation

The humidity values provided by this device are suitable for household use. While humidity measurement is less precise compared to temperature, this meter offers significantly better accuracy than those built into common humidifiers. It helps users determine whether indoor environments need humidification or dehumidification to maintain a healthy living space.

Operation Instructions

Open the battery door as indicated on the back of the device, remove the battery spacer, insert the battery, and close the door. The device will then be operational.
The MODE button switches between clock and alarm display modes and is used to set the current time, alarm, and the 12/24-hour format. The ADJ button adjusts value settings; MEMORY shows stored temperature and humidity values; ℃/°F toggles temperature units; RESET clears all memory and resets to default status.
Press and hold MODE for 1 second to enter time-setting mode. Use ADJ to adjust the flashing minutes and continue pressing MODE to set the hour, 12/24-hour format, month, and day.
The device features an alarm clock and hourly chime which can be toggled on/off. When setting an alarm, the On-the-Hour function activates simultaneously.
Automatic return to current time view occurs after one minute of inactivity in alarm mode. Press ADJ to view calendar display briefly; MAX/MIN button displays stored temperature and humidity extremes since the last reset.
Holding MEMORY for over 2 seconds clears stored minimum and maximum values.
